[hibernate-dev] Is bytecode enhancement enabled by default in 5.3?

[Scott Marlow]

There is a tradeoff in WF deployment, between Hibernate bytecode (runtime)
enhancing class transformers, being registered before CDI deployment, reads
the entity classes.

There is also the tradeoff between Hibernate bytecode (runtime) enhancing
class transformers being registered too late because the persistent unit
uses a datasourcedefinition.

I asked Gail's question for 5.1.x and the answer was no.

Now, for 5.3, I don't understand the answers yet.

Anyway, wanted to mention the above, to share more info with all, as to why
we are asking.

Regards,
Scott
